PlNlON-HOUSING FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 728,615, dated May 19, 1903.

' Application filed December 10,'1902. Serial No. 134,621. (No model.)

To all whom, it may concern:

Be it known that I, OWEN N. RAUSCHEN- BERG, a citizen of the United States of America, residing at Birmingham, in the county of J efierson and State of Alabama, have invented certain new and useful Improvements in Pinion-Housings for Rolling-Mills, of which the following is a specification.

My invention relates to an improvement in the construction of pinionhousings and bearing-boxes for roller-guide mills, and has for its object to so construct and assemble the parts that each of said boxes is removable independently of the others and of the pinion itself.

I employ solid bearing-boxes accurately centered with relation to each other and each constructed in height to correspond with the pitch-circle of the pinions and of the rolls, so that when once assembled and locked in the housing by the vertically-sliding keys no brasses or liners are required to center them or perfect the adjustment of the pitch of the pinions.

My invention consists in the particular construction and arrangement of parts hereinafter described, and more particularly pointed out in the claims, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is an end view of the housing, showing the bearing-boxes assembled and locked in place. Fig. 2 is a top plan view of the same with the caps removed, showing the rolls in dotted lines. Fig. 3 is a detail view of one of the boxes.

In the drawings similar reference-numerals 'refer to similar parts throughout.

The housing 1 is provided with the usual vertical standards 2 integral with the base portion and has a cap 3 suitably bolted to the tops of said standards. Vertically-disposed grooves or recesses 4 are shown in the inner faces of these standards 2, preferably in the center thereof. The bearing-boxes 5 are integral rectangular steel castings, suit-V ably cored to provide bearings for the pinions -6, and having in the center of the two side faces vertically-disposed grooves or recesses 7 of a similar shape and size with the grooves 4. in the standards. These boxes 5 are prepared to fit accurately between the standards and are so centered and proportioned with regard to each other and the desired pitch of the pinions that new ones can be inserted in the manner hereinafter described without disturbing the adjustment of the pinions or the other boxes. These boxes are used in sets corresponding to the different pitch-circles of the pinions in use. Thus where the pinions have an eight-inch pitch their hearingboxes are all eight inches in height and have the same outer contour. Therefore when new ones are inserted the pitch-circle remains unaltered of the several pinions and no adjustment whatever is necessary.

When the parts are assembled in the housing, the corresponding grooves 4: and 7 of the standards and boxes are in alinement and opposite each other, thus forming a continuous guide for the locking-pins 8, which pass through suitable openings in the cap 3 and slide vertically in said guides. These sliding pins lock the boxes securely in place in the housing.

Heretofore in machinery of this character when it became necessary to remove or replace one of the boxessay the lower oneit was necessary to remove the cap, take out the boxes and pinions above the one to be repaired, and finally lift that pinion out, so that I the old box could be removed and the new one fitted on, after which the several parts were replaced in order in the housing, an operation. requiring much time and necessitating the readjustment of parts when the boxes were not accurately centered or spaced, and liners were necessary. All of these disadvantages are overcome by my invention, for it is obvious from my construction that when the boxes have been once centered and adj usted with relation to each other and locked in position between the standards by the sliding key if these keys be raised so as to free any one of the boxes it can be removed by simply slipping it out of the housing, and without disturbing any of the pinions or other boxes a new one can be slipped into position between the standards and locked in place by sliding the keys down, as before.

Though I consider the construction of parts as herein shown and described the preferable manner of embodying my ideas, yet I do not desire to limit myself to the same, but to cover all such minor alterations and changes as do not depart from the spirit of my invention; nor do I desire to limit myself to any particular character of mill or machinery, for it is obvious that my invention is applicable wherever atrain of pinions of this character-is used to transmit motion.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a pinion-housing for rolling-mills, the combination of a base, standards, bearingboxes for the pinions and means engaging each of said boxes and said standards for locking said boxes positively in place and whereby they may be independently removed, substantially as described.

2. In a pinion-housing for rolling-mills, the combination of a base, vertical standards thereon, a plurality of bearing-boxes for the 'pinions centered with relation to each other,

and positive locking means interposed between their side walls and said standards and movable to permit any of said boxes to be independently removable, substantially as described.

3. In a pinion-housing for rolling-mills, the combination of a base, vertical standards thereon, a plurality of bearing-boxes for the pinions, and vertically-movable positive locking devices engaging the side walls of said standards and said boxes, which latter are independently removable, substantially as described.

4. In a pinion-housing forrolling-mills, the combination of a base, vertical standards thereon, pinions, integral bearing-boxes for said pinions centered with relation to each other and each of a height corresponding to the pitch-circle of said pinions, and verticallymovable keys to lock said boxes in place between said standards and whereby they may be independently removed, substantially as described.

5. In a pinion-housing for rolling-mills, the combination of a base, vertical standards, there being vertically-disposed grooves in the inner faces of said standards, a plurality of bearing-boxes for the pinions, there being vertically-disposed grooves in the side walls of said boxes corresponding to the grooves in said standards, and keys to lock said boxes in place by entering and engaging the walls of the corresponding grooves in said boxes and standards, substantially as described.

6. In a pinion-housing for rolling-mills, the combination of a base and standardstherefor, a removable cap-plate, bearing-boxes, there being corresponding grooves substantially vertically disposed in the side walls of said boxes and the inner faces of said standards,said cap-plate having openings above the said grooves, and keys passing down through said openings formed by said corresponding grooves and between the plates, to lock said boxes in place between the standards, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
